Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed June 14, 1918. Serial No. 239,985.

To all whom it may concern:

.Be it known that I, CLINTON G. Ti-ionrn, a citizen of the UnitedStates, residing at Rosedale, in the county of Parke and State ofIndiana, have invented certain new and useful Improvements in Car-Doors,of which the following is a specification.

This invention relates to doors of that class which lie when closedflush with the wall or side of the structure to which they are applied,and which are opened by two movementsfirst, bodily outward from the sideof the structure, and secondly, a sliding movement longitudinallyparallel with the side of the structure to uncover the opening.

The object of the invention is to provide a simple and efficientdoor ofthis character which may be swung snugly within the door opening andeasily shifted laterally to open or close it.

Another object is to provide an improved form of hanger or carrlage forsupporting the door.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the c0mbination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of the inven-'tlOn;

In the accompanying drawings Figure 1 represents a side elevation of aportion of a freight car showing this improved door applied and inclosed position,

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a detail vertical section on an enlarged scale taken on theline 3-3 of Fig. 1,

Fig. 4 represents a side elevation of a portion of a car and door withparts broken out and in section, and

Fig. 5 is a detail horizontal section.

In the embodiment illustrated, a portion of a car body 0 is shown, theside wall of which has a door opening to be closed by a sliding door I),the mounting of which constitutes the gist of this invention.

To the door at suitable distances from the opposlte ends thereof arejournaled two rock shafts 1 and 2, which are securely held to the doorby means of bearing clips 3 in which they are free to turn. Each rockshaft is provided at its upper end with an L-shaped crank bend 4c- Thevertical portion of each bond is secured to a carriage in the form of acasting 5 and is adapted to turn therein." These carriages 5 are mountedto travel in an upper horizontally disposed track 6, secured to the wallC above the door opening. Each of these carriages is equipped 6 5 withrollers 7 and 83, mounted on a, shaft 11 in transverse ahnement andwhlch are deslgned one to engage the edge of an upturned flange 9 at thefront of the track and the other the lower face of a laterally extendingflange 10 at the rear thereof. This track 6 is made in the form of ahousing with an opening in its lower wall or bottom through which thecarriages 5 extend and in which they travel, said housing operating toprotect them against the weather. Each of the carriages 5 is shaped tofit and slide easily in the housing 6 and each has a shank or neck 5extending between. the flanges 9 and 10. A lateral extension 5 projectsforwardly from shank 5 and 1s apertured to re ceive the end of one oftherock shafts. A. recess extends upwardly from the base of theextension 5 in whlch roller 7 is mounted,

the side walls of said recess embracing flange 9and operating asguidesto prevent lateral movement of the carriage. It will be seen thatby having roller 7 travel on flange 9, the weight of the carriage willbe support ed by said flange and roller 8 engaging 9O flange 10 willbalance the carriage and cause it to move easily.

The carriages 5 are connected by a rod 12 shown clearly in Fig. 4 whichholds them in properly spaced relation and also operates as a brace.

The rock shafts 1 and 2 have crank por tions 18 and 14; intermediatelyof their ends with which are engaged the opposite ends of a cross bar 15having a bearing 16 midway its ends and in which is journaled one end ofa crank shaft 17. This crank shaft 17 is revolubly mounted in a bearing18 fixed to the outer face of the door D and has a laterally extendinghandle 19 at its lower end designed to fit over a keeper 20 positionedin its path on the door D, said handle having a slot 21 for thispurpose. After the handle has passed over the keeper 20 a key 22 fixedto the door by a flexible element here shown "Fig. 1.

4 a I u a ing shown in closed position as In Fig. 1, the

In the use of this apparatus, the door be key 22 is first removed torelease handle 19, which is swung outwardly thereby rocking the crankshaft 17 and moving the bar 15 longitudinally toward the right, whichcauses the rock shafts 1 and 2 to turn in their bearings 3, which causestheir crank bends or upper ends 4 to swing inwardly and to bodily liftthe door D out of its opening and when it has been so lifted it may bemoved longitudinally on the tracks 6 and 25 to uncover said opening.

To close the door, the operation is reversed.

It will thus be seen that the structure above described is simple andstrong and reliable in its operation and may be readily applied to anycar or building either already made or in the course of construction.

The foregoing description and the drawings have reference to what may beconsidered the preferred or approved form of m invention. It is to beunderstood that I may make such changes in construction and arrangementand combination of parts, materials, dimensions, etc., as may proveexpedient and fall within the scope of the claimed inventio Having thusfully described my invention,

Copies of this patent may be obtained for five cents each, by addressingthe what I claim as new Letters Patent, is

l. The combination with a wall having a door opening, tracks above andbelow said opening, the upper track being in the form of a housinghaving a longitudinal opening in its bottom with an upstanding flange atone side edge of said opening, and a lateral flange at the other side, acarriage mounted in said housing with transversely alined rollerspositioned one to travel on the top edge of said upstanding flange, andthe other on the lower face of said lateral flange, said carriage havinga forwardly projecting lateral extension, a rock shaft carried by anddepending from said extension and rotatable therein, means connected toturn said rock shaft, and means for locking it in one position to holdthe door closed.

2. The combination with a wall having a door opening, a track above saidopening in the form of a housing having a longitudinal opening in itsbottom with an upstanding flange at its outer edge and a lateral flangeat its inner edge, the lateral flange being in and desire to secure by aplane above the upstanding flange, a car-,

riage mounted to travel in said housing having a shank extending throughsaid bottom opening and provided at its lower end with a forwardextension, said carriage having a recess extending upwardly from thebase of said extension, a pintle extending through said shank and havinga roller thereon positioned in said recess to travel on the edge of saidupstanding flange, and another roller to engage the lower face of saidlateral flange, and a rock shaft rotatable in said extension.

In testimony whereof I aflix my signature in presence of two witnesses.
